Reaction Steps

Twenty-eight ml of ethylene glycol and 100 ml of pyridine were added over a 2.5 hour period to a stirred mixture of tosyl chloride (210 g) in pyridine (225 ml), with the mixture being cooled by a water bath. After stirring for several hours, the mixture was shaken with one liter of ice water for about ten minutes and then filtered. The residue was washed with ether, dilute sulfuric acid, water, and finally ether. (Each of the washed liquids was ice cold.) The residue was then dried by vacuum pumping and recrystallized from boiling acetonitrile. The recrystallized residue, yield 75%, had a melting point of 123° to 125° C.
